Further, said cable skeleton is the Hot Wheels shape, and said location division is circular arc.
Further, said cutting part and location division are integral structure.
Further, said screen is an aluminium foil.
Further, said heart yearn comprises the insulating barrier that metallic conductor is outer with being wrapped in metallic conductor.
The beneficial effect of the utility model is: the utility model reasonable in design; Four groups of twisted-pair feeders are fixed in the cavity of said cable skeleton isolation; And said twisted-pair feeder is resisted against the inboard of said location division, can prevent that dislocation and distortion from appearring in data wire in process of production, increases substantially product percent of pass; And help wiring more, make the structure of said twisted-pair feeder keep stable.
Be provided with screen between said twisted-pair feeder and the insulating sleeve, said screen has stronger antinoise signal to be revealed, and the performance that anti-outside electromagnetic interference etc. are excellent has higher transmission rate, and data transmission security, steady, quick plays the better resisting interference effect.

Embodiment
For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Shown in Figure of description, the utility model comprises insulating sleeve 1, is provided with four groups of twisted-pair feeders 2 in the said insulating sleeve 1, and said twisted-pair feeder 2 is by two heart yearns, 3 stranded forming.Be provided with screen 4 between said twisted-pair feeder 2 and the insulating sleeve 1; Said screen 4 is an aluminium foil; Be provided with ground wire 5 in the said screen 4, said insulating sleeve 1 is provided with the cable skeleton 6 that the inner chamber average mark of insulating sleeve 1 is slit into four cavitys 7, and said cable skeleton 6 is the Hot Wheels shape.Said cable skeleton 6 comprises two groups of cutting parts 61 and two groups of location divisions 62, and said cutting part 61 is cross setting, and said cutting part 61 is orthogonal; Said location division 62 is circular arc, and said cutting part 61 is an integral structure with location division 62.
The inner end of said cutting part 61 is connected, and said location division 62 is arranged at the outer end of cutting part 61, and four groups of twisted-pair feeders 2 are arranged at respectively in the said cavity 7, and said twisted-pair feeder 2 is resisted against the inboard of corresponding location division 62 respectively.
Said heart yearn 3 comprises the insulating barrier that metallic conductor is outer with being wrapped in metallic conductor.Said cross symmetric data cable is provided with eight heart yearns 3 altogether, and said eight heart yearns 3 are distinguished with the color that indicates, and said eight heart yearns 3 carry out stranded respectively according to the color of coffee between green between orange, green-Bai between blue between indigo plant-Bai, orange-Bai, coffee-Bai.The stable of said heart yearn 3 structures is the key factor that influences data transmission performance; Therefore the Cross-section Design of the cable skeleton 6 of the utility model is the Hot Wheels shape; Said twisted-pair feeder 2 is fixed in the said cavity 7; And be resisted against the inboard of said location division 62, thereby can well said twisted-pair feeder 2 be fixed in the cavity 7 of said cable skeleton 6 isolation.This structure has improved the structural stability of said twisted-pair feeder 2, has reduced respectively to organize crosstalking between the twisted-pair feeder 2, and then has made the transmission performance of the utility model be able to promote.
